Amorphous elastomeric polyacetaldehyde was prepared in bulk and in solution using cationic initiators. This polymer is the same as Letort's polyacetaldehyde. The acetaldehyde polymerization must be conducted at −40°C. or lower in order to overcome the competitive trimerization or tetramerization. The reactivity of a number of initiators can be modified by using different solvents. The influence of temperature and type of initiator and solvent on the polymerization was studied.
